The Arctic Cod by D H Cushing Pdf

The Arctic Cod: A Study of Research into the British Trawl Fisheries discusses trawl fishing in the North Sea. The book reviews the history of trawl fishing from the seventeenth century until the mid-nineteenth century when it developed into an industry. Scientific studies of the Artic cod begins in 1860 when the Norwegians started keeping record of their catches at Lofoten. Britain starts to keep reliable records of catches in 1929; and the first study of the Artic cod was by Michael Graham in 1949, done in three ships, the R.V. Ernest Holt, G.O. Sars, and Johan Hjort. The book describes the research work done on the R.V. Ernest Holt at the cod grounds near Bear Island. The Artic cod lives in the Barents Sea and spawn in the Vestfjord; it travels between 1,000 and 1,600 miles each year between its feeding and spawning grounds. The text also describes how the study is undertaken at sea including monitoring temperature measurements, mesh-size, blood samples; and of carrying on studies of fish on the markets, such as recording the number of boats catching what kind of fish. The text also discusses the future of fisheries research in the international arena. This book is suitable for marine biologists, environmentalists, marine conservationists, and researchers interested in marine science.

Threats to the Arctic by Scott Elias Pdf

Threats to the Arctic discusses all the current threats to this fragile region, emphasizing the interconnections between many environmental impacts, as well as the teleconnections between events already emerging in the Arctic (ocean circulation changes, melting of sea ice, glaciers and ice sheets) and other parts of the world. The book's aim is to inform readers about the impending, sometimes irreversible changes coming to the Arctic. University students, environmental engineers, policymakers and sociologists with an interest in the role of the Arctic in global change will benefit from the book's unique perspective. As this remote, inhospitable part of the world that few people will ever visit provides amazing insights, we can no longer have an 'out of sight – out of mind’ approach to the environmental upheavals taking place in the Arctic. Provides the most up-to-date information on this rapidly changing, critical part of the world Offers a holistic understanding of the interconnections between global environmental changes and impacts in the Arctic Examines fact-based pressure on politics and industry to preserve Arctic biota and environments

POLAR NIGHT Marine Ecology by Jørgen Berge,Geir Johnsen,Jonathan H. Cohen Pdf

Until recently, the prevailing view of marine life at high latitudes has been that organisms enter a general resting state during the dark Polar Night and that the system only awakens with the return of the sun. Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod.

Fishes of the Last Frontier by Bill Hauser Pdf

Fishes of the Last Frontier answers many of your fish questions and others you haven't even thought of yet in a nontechnical, plain talk voice. Learn about the fishes that are of value or special interest to Alaskans: how fish are able to survive and grow, how they get along with each other--or not--and what they eat, where and how our Alaska fishes spawn, the difference between a red and a redd, and the difference between anadromous and catadromous and why that is important. The author, a fishery scientist with nearly 50 years of experience and training, including more than 30 years in Alaska, describes the life history characteristics of 43 species of fishes valuable or important in some way to Alaskans. He delves into various aspects of biology and ecology of fish and provides insight into how humans and fish interact. The processes of fishery management in Alaska are described. Fishes of the Last Frontier includes fishes from throughout Alaska in fresh, brackish, and marine waters and sport, commercial, and subsistence fisheries. Learn not just how anadromous fish find their way home but also how scientists were able to learn the details. Nontechnical readers have reported the presentations as enjoyable, understandable, and informative.

Arctic Ecology by David N. Thomas Pdf

The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.

Arctic Climate Impact Assessment - Scientific Report by Arctic Climate Impact Assessment Pdf

The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.
